對于運行中的鍋爐，應(yīng)對蒸汽鍋爐外部的可見部分經(jīng)常進(jìn)行檢查，主要檢驗鍋爐管理，鍋爐本體檢驗，安全附件、自控及保護裝置的檢驗，輔機和附件的檢驗，分汽(水)缸、鍋爐范圍內(nèi)管道、支吊架的檢驗，水質(zhì)管理和水處理設(shè)備的檢驗等。必要時，可拆除局部絕熱材料進(jìn)行檢驗。
1、安全附件、自控及保護裝置檢驗
壓力表在最高許可工作壓力處是否劃有紅線標(biāo)記，是否定期檢驗，有無鉛封。壓力表是否指示正確，可用標(biāo)準(zhǔn)壓力表進(jìn)行校驗。安全閥需要校驗安全閥的開啟度和回座壓力，運行時才能校驗，安全閥校驗后應(yīng)有鉛封。
Maximum allowable working pressure gauge in place if marked with red tags, whether regular inspections, with or without seals. Pressure gauge that indicates whether the correct standard gauge available for verification. Valve opening degree and the need to verify the back seat pressure relief valve, the runtime only after verification, check valve should seal.
2、水位表是否清晰，兩側(cè)水位表指示是否一致，閥門等處有無漏水、漏汽。水位表汽、水連通管是否暢通，照明設(shè)備是否完好等。
Water table is clear, both sides of the water table indicates whether the agreement, valves, etc. for leaks, steam leakage. Water gauge steam, water connecting pipe is smooth, lighting equipment is intact and so on.
3、自控及保護裝置，檢查表計控制裝置是否靈敏可靠，自動或手動控制是否能正常轉(zhuǎn)換。
Automatic control and protection devices, check whether the meter is sensitive and reliable control devices, whether automatic or manual control can be properly converted.
4、各類門孔是否嚴(yán)密，有無滲漏和腐蝕。
All kinds of doors are tight holes, leaks and corrosion.
5、消煙除塵、脫硫裝置檢查：煙囪排放物是否達(dá)到國家規(guī)定標(biāo)準(zhǔn)，爐渣及處理爐渣的揚塵是否污染環(huán)境。除塵蛻硫的污水排放是否符合規(guī)定等
Smoke and dust removal, desulfurization unit tests: whether stack emissions meet the state standards, slag and dust processing slag whether environmental pollution. Sulfur dust shed effluent meets the requirements, etc.
